Trace Function Library, Advanced Tracing Utilities for Unreal Engine

Supercharge your gameplay systems with a powerful suite of trace and sweep functions tailored for real-world game logic. The Trace Function Library provides modular, easy to use Blueprint-callable functions for detecting hits, surfaces, visibility, and spatial relationships in a variety of contexts without the boilerplate.

Whether you're building an RTS, third-person adventure, or physics sandbox, this plugin equips you with trace tools that just work.

Key Features

• Camera-Based Tracing: Easily perform line, sphere, or multi-traces from first-person, third-person, or RTS-style perspectives.

• Shape Sweeps: Line, sphere, box, and capsule sweep support with debug visuals.

• Ground & Ceiling Detection: Grab precise surface points above or below any actor perfect for foot placement or obstacle detection.

• Socket Traces: Trace outward from any socket on a skeletal mesh.

• Cone Tracing: Multi-segment cone-shaped field of view logic ideal for AI detection or visibility checks.

• Debug-First Design: Optional debug lines, points, and durations for every function to simplify iteration and visual testing.

Perfect for solo devs, prototypers, and advanced system designers alike cut out the repetitive setup and get straight to results.
